MANUFACTURE (IF IBICOLORED SPECTACLES.

Application filed July 2,\ 1924. Serial No. 723,665.

lenses of transparent or translucent 11121- terial, but of differentcolors or tints, as for instance one of blue or green and one of red ororange color,these spectacles, so called, while of utility mainly inviewing pictures whereby certain novel effects are attained, beingdesigned for use primarily suitable fibrous 7 material, having imposed Ibellishments' fora pl as mediums for advertising, and being gratuitouslydistributed, so that cost of production is an important consideration aswell as simplicity and perfection of form and structure.

To this end the invention consists essentially in the process ofmanufacture herein set forth, and described and claimed specifically, adistinctive feature being the method of plural production in series,whereby the time, labor and cost involved are reduced to a minimumdegree while the resultant product is of uniform character andefficiency.

In the accompanying drawings I illustrate a practical. embodiment of theessential features of my invention by views showing the successive stepsin my process of the manufacture, simultaneously, of any plural numberof eye-glasses of the character designated, although I do not wish tolimit myself to the identical configuration and structure of parts andappurtenances therein shown by way of :exemplification, since changesmay be made in minor details, and mechanical expedients resorted to,with like results, and without departing from the spirit and intent ofmy invention in this respect.

With this understanding a Fig. 1, represents a face view of a portion ofa sheet of paper, cardboard, or other thereon, as the first step in theprocess of manufacture, the reading matter and ema 'ty of. spectacles,

the medial portion on either side of the prescribed line of fold beingshown, and both ends of the sheet being broken away, the sheet beingotherwise full size;

Fig. 2, is a View like unto Fig. 1, showing the sheet perforated withthe lens openings.

which are coincidental when the sheetis folded;

Fig. 3, is a view of the reverse or inner side of the full sheet,reduced to approximately one half size, of the sheet prepared.

as in Fig. 2, and showing the strips of trans parent'colored lens mediapositioned overthe lens openings on one half of the sheet preparatory tothe'folding over thereon of the other half of the sheet;.

Fig. 4, is a front view of a folded sheet Fig. 5, is a rear view of theportion. of. completed sheet shown in Fig. 4;

Fig. 6, is a view of one side of the completed roduct; and

Fig. a transverse section thereof taken upon plane of line 7-7, Fig. 6.

The superimposable basic mount sheets or portion of the layers S, S arecomposed ofv anysuitable material adapted to the purpose, such as paperof suitable thickness, cardboard, or in fact any fibrous oreven. textilematerial of requisite consistency and pliability. These V superimposablemount sheets S, S are preferably although'not necessarily formed of onepiece of material, as illustrated in Figs. 1, 2 and 3, of the drawings,with a scored or otherwise prescribed line of fold' 5 s, between them,the sheet or section S, be- I, ing what may be designated as the frontlayer of the two ply unitary mount sheet resultant from the permanentimposition of the two figures S, S, one upon the other,

back to back, as hereinafter set forth In \i other words, while thereare certain advan tages in including and forming both sections S, S ofthe basic mount in a single preliminary sheet, such, for instance, asexpeditious printing and manipulation, this method is not indispensable,since the sections or plies S, S, may consistof separate-o 1y printedand prepared sheets for superimposition to form the bas1c support,between them, for the lens material L, L I

With this explanation, and following the specific method of manufactureillustrated 1'1 sheet or section S, S are printed or otherw1se inthedrawings, the outersurfaces of each m q l -the h d re Wi s matter,advertising, or embellishments, as

indicatectin Fig. 1, of the drawings.

The basic sections S, S then are diestamped to form the sights or lensopenings 8, s, illustrated in Fig. 2, of the drawings, after which thecolored lens strips L, L are positioned (as indicated in Fig. 3, of thedrawings) on the inner or back side of one or the other of the basicsections S, S and the latter are then superimposed, back to back, oneupon the other, and united integrally with the said colored lens stripsL, L between them. This permanent joining of the basic sections S, Sback to back, with the transparent color strips L, L interposed betweenthem, may be effected by any suitable means, and I do not limit myselfin this respect, as any adhesive or equivalent unitary incorporativeexpedient may be resorted to, as may be found most suitable in practice,in accordance with the nature and object of the finished productdesired.

The transparent mediums L, L are illustrated symbolically in thedrawings respectively as of contrasting colors, blue and red, althoughother analogous colors may be used. These colored transparent lensmediums may consist of strips of gelatine or any equivalent thereof; andmay be of other appropriate contrasted colors than those indicatedherein.

The use of strips L, L, of colored transparent medium covering aplurality of sight or lens holes 8, s, as indicated in Fig. 3, of thedrawings is obviously an advantage in 1 the process of manufacture,insuring uniformity and perfection of alignment, and reducing labor andmanipulatlon to a IIllI1l mum degree in this respect.

In fact it will readily be seen that by my process of manufacture aneffective, stand- 7 ardized production may be attained with a minimumexpenditure of time, labor and cost, it being understood that theindividual 3 spectacles or eyeglasses are die-stamped from the preparedsuperposed and integrally united basic sheets S, S portions of which areshown in Figs. 4 and 5, resultp ing in a plurality of specific productssuch 5 as shown in Figs. 6 and 7, of the drawings,

in whichs, represents the nose bridge, and

8 an extension to serve as a convenient finger hold to facilitate theuse of the lenses L, Li the term lenses being used herein in afigurative sense as designating the colored eye screens or shades, theprovision and use of which is the ultimate object of my invention.

It is to be understood in this connection that the configuration of thecompleted product shown by way of exemplification in Fig. 6, of thedrawings, may be varied without deviating from the spirit and intent ofmy invention in this respect; and that lettering, etc. shown as imposedthereon is simply indicative of the utility of the product as anadvertising medium for gratuitous distribution.

Obviously the details and steps of manufacture may be varied more orless within the scope of my invention, which consists essentially, firstin preparing the outer surfaces of the basic sheets S, S byimposingthereon the reading matter or embellish ments to be shown on thecorresponding outer surfaces of the completed product; then die- .j

stamping the said basic sheets to form the"? lens openings 8, s; thenun1t1ng said sheets integrally, with the transparent colored mediumsbetween them, and finally diestam we ing out the individual spectaclesor glasses rom the basic structure thus attained.

It is to be understood that by the terms v feye-glasses or spectacles asherein used. I mean to imply substitutes for theopticalappliances thusordinarily designated.

It is to be understood that my basic sheets I may be made fromcontinuous webs: of material fed from rolls.

What I claim as my invention and desire: in

to secure by Letters Patent, is:-

1. The method of manufacturing bi-col-g ored spectacles consisting inimposing reading matter on the exterior surfaces of basic mount sectionsstamping out sight openings in the said basic sections, applying atrans' transparent media between said sections and folding the saidsections one upon each other and enclosing the said media.
